The 6-foot-1, 175-pound guard from Encino, Calif., picked the Wildcats over UCLA, Gonzaga, Kansas and USC, per ESPN. If his commitment holds, he’ll become the first five-star point guard commit to land at Arizona since Josiah Turner chose Arizona in 2011.

“They are starting to do a lot more ball screens, which fits my game,” Williams told ESPN. “Also, my relationship with the coaching staff is great. That’s very important.”

Williams is ranked as the No. 16 prospect in the 2018 class, according to ESPN’s rankings, and joins 5-star power forward Shareef O’Neal as a commitment to Arizona. The Wildcats had also gained a commitment from 2018 recruit Emmanuel Akot, but he reclassified to the 2017 class and will be able to play for Sean Miller’s team this coming season.

Arizona will continue to build its 2018 recruiting class and is most notably in the mix with the nation’s top overall prospect, forward Marvin Bagley III.
